An explicit assumption of continuity is used to generate a fuzzy implication operator, which, yields an envelope of possibility for the conclusion. A single fuzzy rule A~B entails an, infinite set of possible hypotheses A'~B' whose degree of consistency with the original rule, is a function of the "distance" between A and A' and the "distance" between B and B'. This, distance may be measured geometrically or by set union/intersection.

Why it's free to use
- Filed June 25, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 25, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 25, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
